Thepa: phofo e putsoa-pherese. Ha e qhibilihe ka metsing, e qhibilihang ka sodium sulfide solution e botala bo boputsoa. E boputsoa-pherese ka har'a asiti ea sulfuric e kopaneng 'me e hlapolotsoe ho putsoa e lefifi. Dae e fetoha 'mala o mosehla o bobebe oa mohloaare ka tharollo ea phofo ea alkaline ea inshorense,' me 'mala oa pele o ka tsosolosoa ka mor'a oxidation; Ka ho feletseng faded ka sodium hypochlorite tharollo; E fetoha pherese e lefifi ho sulfuric acid e kopaneng

Mokhoa oa tlhahiso: nitrosation ea phenol sodium nitrite le sulfuric acid ho hlahisa p-nitrosyphenol, condensation le o-toluidine e qhibilihisitsoeng ka sulfuric acid, phokotso le vulcanization ka sodium polysulfide e nang le palo e itseng ea sebabole, ebe ka oxidation ea khase, 'me qetellong ka ho hloekisa. , ho omisa, ho silakanya le phekolo e tloaelehileng ho hlahisa lihlahisoa.
